A neighbor of Oscar Pistorius has returned to the stand to give evidence in the star athlete's murder trial in South Africa.

Charl Johnson, who says he heard gunshots and a woman screaming on the night Pistorius killed girlfriend Reeva Steenkamp, was testifying at Thursday's proceedings. Johnson left the stand Wednesday to retrieve some notes he said he made after Steenkamp's shooting death.

Lead defense lawyer Barry Roux was cross-examining Johnson, who lives around 177 meters (193 yards) from the house where Pistorius killed Steenkamp on Valentine's Day last year.

Pistorius, a double-amputee runner who competed at the 2012 Olympics, is charged with murder with premeditation after shooting Steenkamp through a toilet door. Pistorius says the killing was accidental because he thought she was an intruder in his home.
